[linux-dvb] How to run ca_zap?

One silly question...how do you use ca_zap? I've tried every combination
of tzap and ca_zap and got nothing to show for it and I have no idea what
I'm looking for...

Here's the output from ca_zap -c channels.conf -t ter -n "MTV" & tzap -c
channels.conf -r "MTV"

ES Info Length looks funny, but I still need to know how to work these
things and what signals success.
